Arguments
x
|

Graphical parameters (see par ) may also
be supplied as arguments to this function.

Description
Creates the banner of a mona
object.Details
Plots the separation step at which clusters are splitted.
The observations are given in the order found by the mona
algorithm, the
numbers in the step
vector are represented as bars between the observations.
When a long bar is drawn between two observations,
those observations have the same value for each variable.
See chapter 7 of Kaufman and Rousseeuw (1990).Value
a NULL value is returned.Side Effects
A banner is plotted on the current graphics device.NOTE
In the banner plot,
observation labels are only printed when the number of observations is
limited to less than 35, for readability.
Moreover, observation labels are truncated to at most 5 characters.References
